HML32 + sulphur+copper at 10-14 day intervals Spray with 0.5%Protectorhml+ sulphur at 10-14 day intervals. Add copper if required for the control of other diseases. Final spray with HML32 + sulphur before inflorescences opening. Copper is

• ptional but recommended as it provides

a higher level of powdery mildew control

HML32 + sulphur + copper at 10-14 day intervals First application HML32 + sulphur + copper. Follow up with 0.5%Protectorhml+ sulphur at 10-14 day intervals. Add copper if required for the control of

• ther diseases

HML32 + sulphur + copper at 10-14 day intervals First application HML32 + sulphur + copper. If season presents high risk, continue with HML32 + sulphur + copper at 10-14 day intervals. Otherwise, follow up with 0.5%Protectorhml+ sulphur at 10-14 day intervals. Add copper if required for the control of other diseases
